Old grenades found by pipe digger in Ubon

Three grenades were discovered while a worker was excavating soil to lay a tap water pipe on Chayangkoon Road in Ubon Ratchathani's Muang district on Friday night.

The grenades were believed to be live and could have exploded with pressure or heat.

Muang Ubon Ratchathani Police Station investigator Lt-Colonel Sittichok Piboonsaksophol said Kamol Boonme, 30, was using a back?hoe on the roadside when he found the rusty grenades, which were 60mm, 81mm and 120mm in size.
